Answer» Given that profit was divided between them in the ratio 3 : 1 Let us consider SOHAN joined the BUSINESS after (12 - x) months ⇒ (1,00,000 × 12)/ (40,000 × (12 - x)) = 3/1 ⇒ 12,00,000 = 3 (4,80,000 - 40,000x) ⇒ 12,00,000 = 1440000 - 1,20,000x ⇒ 1,20,000x = 14,40,000 - 12,00,000 ⇒ 1,20,000x = 2,40,000 ⇒ x = 2,40,000/1,20,000 = 2 ∴ After 2 months Sohan JOIN the business |
